What Size Hail Will Damage Your Roof?
Living in Granbury, TX, homeowners are no strangers to unpredictable weather, especially during hail season. While not every hailstorm results in visible damage, the truth is that even small hailstones can compromise your roofing system. Understanding the sizes of hail that pose a threat to your roof is essential to protecting your home and addressing issues before they escalate.
At DT Roofing, we’ve seen firsthand how different types of hail impact a variety of roofing materials. Our experience across Granbury and the surrounding areas shows that even seemingly minor storms can cause significant issues, especially when left unchecked.
Hail Size and Its Impact on Roofs
Not all hailstones are created equal. Their size, speed, and density determine how much damage they inflict on your roof. Here’s a breakdown of the most common hail sizes and the level of damage they typically cause:
Pea-Sized Hail (¼ inch)
Pea-sized hail is the most frequent type but rarely causes roof damage on its own. However, repeated storms with this size of hail can weaken your shingles over time, especially if your roof is already aging or compromised.
Marble to Dime-Sized Hail (½ inch to ¾ inch)
This size starts to pose a risk, particularly to roofs with older or worn shingles. Over time, cumulative exposure can lead to granule loss and minor indentations that compromise the protective surface of your roof.
Nickel to Quarter-Sized Hail (7/8 inch to 1 inch)
This is where the real concern begins. Asphalt shingles, especially 3-tab models, are vulnerable to cracking and bruising under hail of this size. Metal roofs may suffer from cosmetic dents, while clay tiles can chip or break.
Golf Ball to Tennis Ball-Sized Hail (1½ inches to 2½ inches)
Large hailstones like these can cause immediate and severe damage. Shingles can be punctured, flashing can be bent, skylights cracked, and even underlying roofing layers compromised. If your roof is hit with hail this size, a professional inspection is critical.
Roofing Materials and Hail Vulnerability
The type of roofing system you have plays a major role in how well it resists hail impact. Asphalt shingles, the most common roofing material, are particularly susceptible to bruising and granule loss. Metal roofing tends to be more resistant structurally but can dent from larger hailstones. Clay and concrete tiles offer good resistance but may shatter if struck by high-velocity hail.
Choosing durable materials and high-quality installation methods is key to long-term performance. Many Granbury homeowners opt for Owens Corning roofing systems for their high impact resistance and strong manufacturer warranties. Working with an Owens Corning Platinum Preferred Contractor like DT Roofing ensures you get materials and workmanship that meet industry-leading standards.
Why Small Hail Still Matters
Even hail that doesn’t immediately look destructive can shorten your roof’s lifespan. Granule loss exposes the asphalt layer of shingles to UV damage, accelerating deterioration. Hairline cracks can allow moisture to penetrate, leading to leaks and structural issues down the line. That’s why post-storm inspections are so important — damage isn’t always visible from the ground.
What to Do After a Hailstorm
After a hailstorm passes, don’t assume your roof is intact just because you don’t see broken shingles or leaks. Here are a few immediate steps to take:
- Visually inspect from the ground for signs like shingle granules in gutters or downspouts.
- Check outdoor areas like decks, cars, or mailboxes for dings or dents as signs of hail intensity.
- Schedule a professional inspection with a certified roofing contractor to document any damage and assist with insurance claims.
Avoid attempting to climb on the roof yourself — not only is it dangerous, but you might miss subtle damage only an experienced eye can detect.
Insurance and Roof Repair After Hail
If hail damage is confirmed, your homeowner’s insurance policy may cover repairs or replacement, depending on your deductible and coverage terms. Working with a contractor experienced in insurance restoration, like DT Roofing, can simplify the claims process. Our team knows how to document damage properly and advocate for the repairs you need.
Prevention Tips and Maintenance
While you can’t prevent hail, you can improve your roof’s ability to withstand it:
- Invest in impact-resistant shingles.
- Schedule annual roof maintenance and inspections.
- Clear debris from gutters and valleys.
- Check that flashing and ventilation components are secure.
Preventative steps not only protect your roof but may also earn you insurance discounts.
